1 Samuel 25:4-8
4-8David, out in the backcountry, heard that Nabal was shearing his sheep and sent ten of his young men off with these instructions: "Go to Carmel and approach Nabal. Greet him in my name, 'Peace! Life and peace to you. Peace to your household, peace to everyone here! I heard that it's sheep-shearing time. Here's the point: When your shepherds were camped near us we didn't take advantage of them. They didn't lose a thing all the time they were with us in Carmel. Ask your young men—they'll tell you. What I'm asking is that you be generous with my men—share the feast! Give whatever your heart tells you to your servants and to me, David your son.'"
9-11David's young men went and delivered his message word for word to Nabal. Nabal tore into them, "Who is this David? Who is this son of Jesse? The country is full of runaway servants these days. Do you think I'm going to take good bread and wine and meat freshly butchered for my sheepshearers and give it to men I've never laid eyes on? Who knows where they've come from?"
